DEVICE FOR OBLIQUE FIRING.

Application filed February 21, 1919.

To all whom it may concern:

Be it known that I, ALEXANDER T. FISCHER, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Devices for Oblique Firing, and declare the following to be a full, clea 3, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawin s, which form a part of this specification.

' y invention relates to an improvement to be attached to fire arms, more especially hand fire arms, which will enable the user of such fire arms to direct the bullet therefrom at an angle from that of the line of sight as is now practised. This improvement is especially desirable in airplane usage in war, as it enables the observer to shoot over the side ofthe airplane and direct his bullet to an object beneath him without being obliged to hold the fire arm in a vertical or nearly vertical position and without being exposed to fire from his adversary. Soldiers also by its use may fire over parapets without exposure to adverse fire.

It consists in an attachment that can be applied to fire arms in ordinary use whenever special service of the kind referred to is desired.

In the drawings:

Figure 1 shows the device attached to a revolver or pistol, and suspended from an attachment to an airplane or other carriage in such manner that it can be held in any position.

Fig. 2 is a. longitudinal sectional view of the directing device proper. r

Fig. 3 shows it combined with a rifle and bayonet.

Fig. 4 shows the device with bayonet partially sectioned before being attached to a rifle.

Fig. 5 shows the device attached to a rifle together with a reflecting sight, preferably periscopic, in which the fire can be directed with great accuracy.

In the drawings similar letters refer to similar parts: i

In the drawings A represents a fire arm as a revolver of the conventional type. B is the deflecting device shown in section in Fig. 2, secured to the muzzle of the firearm at C, the end of the device being somewhat en larged to be screwed over the muzzle. It is Specification of Letters Patent.

Patented May 25.19 20. Serial No. 278,501.

provided with a bore D of the same size as the caliber of the bore of the firearm, and which registers with the bore of the firearm. On the explosion of the cartridge the bullet is forced through the firearm in the usual manner and through the bore of the directing device C, in which it is given a turn or angle from the direction of the bore of the firearm in proportion to the curvature of the device. This curvature may be varied if desired to suit various conditions. It can be made so that the bullet will emerge at right angles to its initial direction. It is shown as applied to rifle E in Fig. 3 in combination with a bayonet F, the bore being shown in section at D. As there is nothing new to the firearms employed it is unnecessary to describe them. In Fig. 5 there is shown mounted upon the firearm a periscope G, which at H is bent at an angle to correspond to the angle of the attachment D to the firearm, so that the direction of the bullet in leaving this attachment at an angle to the firearm is parallel with the optical rays entering the periscope. At M in the angle of the periscope a mirror is placed which reflects the lines of light so that they will follow the axis of the periscope thereafter which corresponds with the general direction of the bore of the rifle. As periscopes are common and there is no modification except by the angle H and the mirror M it is unnecessary to describe it any further. Means for adjusting the periscope may be provided as the rack and pinion N. This is also a common feature and needs no description.

Above the observer in an airplane or other carriage can be erected a gallows frame as shown in Fig. 1, consisting of supports P P and a cross ar'n Q. Upon this cross arm is a traveling carriage R secured with a thumb screw R to hold it in any position. Preferably a chain S supports the firearm at its center of gravity together with the device B attached, in such a manner that it can be swung in any direction or position. By be ing traversable from side to side on the cross-bar and held in position by means of the set screw R it possesses every facility of direction. The observer in the" airplane can therefore grasp the firearm and fire it in any direction and by virtue of the curvature of the bore at T he can fire under the airplane without reaching over the side to any extent, therefore being able to advantageously fire oven thejside. It is obvious that the barrel of the firearm and the curved extension could be made integral without departing from m invention.

Having thus escribed my invention what dam is The combination of a firearm with baythe projectile.

whereof I sign this specifi- In testimony cation.

- ALEXANDER T. FISCHER.
